rs6000: don't expect __ibm128 with 64-bit long double [PR99708]

When long double is 64-bit wide, as on vxworks, the rs6000 backend
defines neither the __ibm128 type nor the __SIZEOF_IBM128__ macro, but
pr99708.c expected both to be always defined.  Adjust the test to
match the implementation.

	PR target/99708
	* gcc.target/powerpc/pr99708.c: Accept lack of
	__SIZEOF_IBM128__ when long double is 64-bit wide.
